Wood consumption
Jøtul F 350 has a nominal heat output of 8,0 kW. Use of wood,
with nominal heat emission: Approx. 1,8 kg/h. Another important
factor for proper fuel consumption is that the logs are the correct
size. The size of the logs should be:
Kindling:
Length: 30 cm
Diameter: 2 - 5 cm
Amount per fire: 6 - 8 pieces
Firewood (split logs):
Length: Approx 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 2,0 kg
Amount per load: 3 pieces
Nominal heat emission is achieved when the air wash vent is
.

3.0 Installation
3.1 Floor
Foundations
It must be ensured that the foundations are dimensioned for
the fireplace. Cf. «2.0 Technical data» for specification of weight.
It is recommended that flooring which is not fastened to the
foundations – so-called floating flooring – is removed during
installation. .
Combustible floor protection
If the fireplace is to be mounted on a combustible floor, cover
the floor under and in front of the fireplace with a plate made
of metal or other non-combustible material. The recommended
minimum thickness is 0.9 mm.
Any flooring made of combustible material, such as linoleum,
carpets, etc. must be removed from under the floor plate.
Requirement for protecting combustible
flooring in front of fireplace
The front plate must be in accordance with national laws and
regulations.
Contact your local building authority regarding restrictions and
installation requirements.
3.2 Walls
Distance to wall made of combustible material
- see fig. 1.
You may use the fireplace with an uninsulated flue pipe provided
the distances to walls made of combustible materials are as
shown in fig. 1.
Distance to walls covered by a firewall
Contact your local building authority regarding restrictions and
installation requirements.
Firewall requirement
The firewall must be at least 100 mm thick and be made of
brick, concrete-stone or light concrete. Other materials and
constructions with satisfactory documentation may also be
used.
Distance to non combustible walls
By non combustible one means a non load-bearing wall of solid
brickwork/concrete.
Contact your local building authority regarding restrictions and
installation requirements.
3.3 Ceiling
There must be a minimum distance of 1000 mm to a combustible
ceiling above the fireplace.
3.4 Chimneys and flue pipes
• The fireplace can be connected to a chimney and flue
pipe approved for solid fuel fired appliances with flue gas
temperatures specified in «2.0 Technical data».
• The chimney's cross-section must be at least as big as the
flue pipe's cross-section. See «2.0 Technical data» when
calculating the correct chimney cross-section.
• Several solid fuel fired appliances can be connected to the
same chimney if the chimney's cross-section is sufficient.
• Connection to the chimney must be carried out in accordance
with the installation instructions from the supplier of the
chimney.
• Before making a hole in the chimney the fireplace should be
test-mounted in order to correctly mark the position of the
fireplace and the hole in the chimney. See fig. 1 for minimum
dimensions.
• Ensure that the flue pipe is inclined all the way up to the
chimney.
• Use a flue pipe bend with a sweeping hatch that allows it
to be swept.
Be aware of the fact that it is particularly important that
connections have a certain flexibility in order to prevent
movement in the installation leading to cracks. N.B. A correct and
sealed connection is very important for the proper functioning
of the product.
Chimney draught; See «2.0 Technical data». If the draught is
too strong you can install and operate a flue damper to control
the draught.
